Nationally representative historical trends in neonatal infantile hemangioma (IH) diagnosis have not been previously assessed. Using the National Hospital Discharge Survey (NHDS), trends in IH diagnoses were assessed according to race and sex. Findings confirmed prior research that female and white newborns are more likely to be diagnosed with IH, and a statistically significant increase in IH diagnoses was observed in white, but not in nonwhite, infants.
